The only available related note under the 'Education' section involves the 1099-Q. There were no withdrawals so that form does not apply. I just need to deduct for my contributions (at the $3,000 limit).
Yes, there are couple of tax benefits for 529 plan contributions in MN.
There is a non-refundable credit of up to $500 available for certain residents. The amount of the credit is 50% of the contribution up to $500, but the credit begins to phase out at $78,340 of adjusted gross income (AGI), and is completely phased out at AGI of $103,340 or $166,010 married filing jointly.
If you do not claim the credit, you can subtract from your federal adjusted gross income (AGI) the "net contributions to qualified accounts" up to $1,500 or $3,000 for married filing jointly.
These options will be available to you in the MN state tax return interview.
